Obesity phenotype in relation to gene polymorphism among samples of Egyptian children and their mothers
Obesity is complex heterogeneous disease controlled by genes, environmental factors, and their interaction. Genetic factors account for 40–90% of the body mass index variations. Body mass index (BMI) of children correlates more closely with maternal than paternal BMI. So, this studu was aimed to inv...
